awesome

Worrying question, what temp is needed to ignite the Earths atmosphere?

This might be what happened at the famous "Tunguska event" back in the early 1900's. An enormous blast, but no "fragments" to be found. People thought that was a comet, but this sheds some new light on the matter. It might have been an asteroid after all.

jesus would not let his flock perish in such cruel ways. It will explode over Iran

lol no. We got the ideas from the bomb from theoretical experiments and physics. This is derived from nature, but there was nothing in nature that we witnessed which was even close to something like the atom bomb. Enormous energy release, definitely. But the mechanism for this release is totally different. Oh wow! Krakatoa was powerful! That's not the point imbecile. Nuclear weapons are completely difference than natural volcanic events.

You can agree with me, or disagree. You can tell me I'm right or wrong, I'm always up for a healthy conversation or healthy argument.

What I won't do, is get into an argument with a person using profanity or throwing insults at other people to get their point across.

Using profanity or cursing only shows your intellect since curse words are the easiest words to remember when learning a new language.

You can make your point without using those words, if not, don't even bother replying.

[ojmardueno]

We actually got the ideas from studying nature itself.

How do you think the Sun works? It's a constant nuclear reaction that produces energy, that's how most if not all stars work.

There is even evidence that, here on earth, we had a naturally occurring nuclear chain reaction about 2 billion years ago in Gabon, West Africa. They are even studying it right now to see if they can get ideas on how to operate our modern nuclear reactors more safely and efficiently.

[ojmardueno]

We wouldn't know it was possible unless we had evidence that it could be done.

[Icix1]

incorrect, many theoretical models and equations can predict various phenomena before they are directly observed. This is a clear example of taking a mathematical model and applying it.

[locochepo]

science is so cool!

[ojmardueno]

So what you're saying is, humans didn't invent the nuclear bomb, we just copied off of nature, or space, if you will?

What we think we know now is nothing to what we will learn in the next millennium, and the millennium after that, and so on, and so on.

I just hope we're still here.

[Icix1]

No, we invented the bomb you idiot. It's just the effects of the a very large explosion are similar to the effects that one would get from an impact. We haven't seen anything like this in nature, ever.

[ojmardueno]

Technically, you're right. We humans haven't seen this before, but just because we haven't seen it, doesn't mean it hasn't happened before.

Also, we wouldn't have thought that it was possible to create a weapon with the destructive power of a nuclear bomb, if we hadn't seen huge explosions in nature before.

Volcanoes are nature's nuclear weapons.

The biggest explosion ever witnessed by man, here on earth was not manmade, but made by nature itself.

[ojmardueno]

Krakatoa, a volcano in Indonesia was the biggest and loudest explosion ever heard by man. It was heard more than 3,000 miles away from the blast.

The explosion was 13,000 times more powerful than the Hiroshima bomb.

So technically, nature paved the way for us to create those bombs, but you would know that if you actually watched the PBS special on Krakatoa.

[Moirera]

@ojmardueno

I'm not sure about audible explosions but Krakatoa was the third "largest" by a non super-volcano. Lake Taupo in New Zealand was the largest. It was the most recent event to cause the maximum rank 8 of the Volcanic Explosion Index (100 times more powerful than Krakatoa). Even though it happened 26,500 years ago.

Mount Tambora was a rank 7 (10 times more powerful than Krakatoa) occured only 70 years before Krakatoa as well.

[Icix1]

"Volcanoes are nature's nuclear weapons."

LOL

Oh, because volcanoes are fueled by nuclear chain reactions?

[jordythegreat]

we kinda did copy the nuclear bomb from nature with nuclear elements that we saw that destroyed large amounts of lands and cities. you know that to make a such nuclear explosion is splitting the molecule of that particular nuclear element.
